Abstract
A locking system for an enclosure, including a control bracket mounted to a door of the enclosure and configured to slide in a longitudinal direction along a guide rod running through a pin bracket of the control bracket. The control bracket further includes a latching pin to secure the door of the enclosure. A handle mechanism has a push rod that causes the control bracket to slide along the longitudinal direction, also causing the latching pin to move into a position that secures the door.
Claims20
A locking system for an enclosure, comprising:
- a control bracket having a main body defining a main body plane and a pin bracket defining a pin bracket plane,
- wherein the control bracket is configured to slide along a control bracket axis in the main body plane,
- wherein the main body plane is perpendicular to the pin bracket plane,
- wherein the pin bracket has first and second through holes extending through the pin bracket;
- a guide rod extending through the first through hole of the pin bracket;
- a latching pin extending through the second through hole of the pin bracket;
- a locking flange adjacent the latching pin;
- a handle having a push rod configured to engage with the control bracket;
- and
- an indicator that provides a notification to a user when the latching pin has engaged the locking flange.

A locking system for an enclosure having an enclosure opening on one side and a locking flange having a locking flange through hole extending therethrough, the locking system comprising:
- a door hingedly attached to the enclosure at a side of the enclosure opening;
- a control bracket mounted to the door and configured to slide along a control bracket axis;
- a handle and a handle mechanism mounted to the door,
- wherein the handle mechanism is configured to cause the control bracket to slide along the control bracket axis when the handle is rotated;
- a two-stage cam mounted to the enclosure, the two-stage cam having a ramp portion leading to a plateau portion;
- a roller rotatably mounted to the control bracket and configured to engage the ramp portion and the plateau portion of the two-stage cam;
- and
- a latching indicator that provides a notification that the door is securely closed when the roller is in contact with the plateau portion of the two-stage cam.
